H₂S in a Wastewater Treatment Plant

Yara’s YaraNutriox offers a preventive solution against H₂S and the odour pollution that comes with it. This solution includes a full set of services:

• On-site diagnosis to identify the source of hydrogen sulphide
• Preventive treatment
• Dose monitoring

Dynamic YaraNutriox dosing allows sites with H₂S problems to eliminate odour, and prevent the exposure of WWTP employees to this toxic gas. Specially developed dosing equipment responds to the specific flows and other characteristics of the network to achieve the optimum usage rate.

Unlike some other treatment methods, controlled dosing of YaraNutriox has no negative impact on the wastewater treatment process and YaraNutriox can also fight against the corrosive effects of hydrogen sulphide.

Yara has developed YaraNutriox, a process that prevents septicity caused by lack of oxygen in the pipes of the sewer network and of the WWTP. YaraNutriox is a mixture of nitrates specially developed by Yara, with proven results in hundreds of sewer systems to fight against the corrosive effects of hydrogen sulphide. Communities throughout the world, such as York, Paris, Cologne and Montreal, use YaraNutriox against H₂S
